Introduction:
Frederick Winslow Taylor, also known as the father of scientific management, developed several principles of management to improve productivity and efficiency in the workplace. These principles were aimed at optimizing the performance of workers and increasing overall organizational effectiveness.

Explanation:
a) Maximum not restricted output:
Taylor believed that managers should strive to achieve the maximum output from each worker, rather than restricting their performance. He emphasized the importance of setting high production goals and providing workers with the necessary tools, training, and incentives to reach those goals.

c) Harmony not discord:
Taylor advocated for a harmonious work environment where there is mutual trust and cooperation between workers and management. He believed that conflicts and disputes should be resolved through open communication and collaboration, rather than through confrontation or hostility.

d) Science, not rule of the Thumb:
Taylor emphasized the use of scientific methods and principles to make management decisions, rather than relying on traditional and arbitrary rules of thumb. He believed that decisions should be based on careful observation, analysis, and experimentation, rather than on personal opinions or past practices.

b) Functional foremanship:
Functional foremanship is not one of the principles of management given by Taylor. It was actually a concept developed by Taylor's associate, Henry Gantt. Functional foremanship involves the division of supervision into specialized roles, with different supervisors responsible for specific functions such as planning, organizing, directing, and controlling.

Conclusion:
In conclusion, out of the given options, the principle of management NOT given by Taylor is "b) Functional foremanship." This concept was developed by Henry Gantt, while Taylor focused on principles such as maximizing output, promoting harmony, and applying scientific methods in management decisions.
